This invention relates to a heating unit partioularly for use in connection with automobiles. The said invention relates particularly to the type of heating unit wherein a stream of air to be heated is directed over a heating element. The said heating element is pre'ferably of the hot water type associated With the cooling system of the automobile. Certain features of the invention, however, apply equally to any other suitable type of heating element such as an electrical resistance unit.

The particular` feature of the present invention resides in the mounting of a deflector over the face of the heater capable of being rotated to deflect the heated air in any desired direction. Another feature of the invention resides in the association of shutters forming the defiectorfor further deflecting the heat in angular relation to the heating unit in the direction determined by the rota-ry positioning thereof. I

Still another feature of the invention resides in the provisi'on of a suitable handle attached to the deflector for permitting the ready and convenient manual manipulation thereof for rotary positioning.

Still a further feature of the invention resides in the provision of an insulating sleeve mounted in connection With the intake and return pipes for the hot water circulating system wherein it passes' through and is secured to the dash board of the vehicle. By this means the tubes are spaced and insulated from the dash board 'and the attaching members through which they pass. In addition thereto they are yieldingly supported in spaced relation so that vibration will be minimized and heat lost by oonvection will be reducedI o The full nature of the invention Will be more fully nnderstood from. the accompanying drawing and the following description and claims:

Fig. 1 is a front elevation of the heater with the. defiector mounted thereon. Fig. 2 is a rear elevation of the front face plate of the heater showing the mounting of the deflector on the rear face thereof. Fig. 3 is a central Vertical seotion through the heater and deflector. Fig. 4 is an enlarged section taken on the line 4-41 of Fig. 2.

The heater comprises a radiator core 10 supported in an upper header 11 and a lower header 12 connected to the water cooling sysas tem of an internal combustion engine mounted in an automobile through the Water conduits 13. The radiator core and headers are supported in a suitable casing 14 which is mounted upon the dash board 15 of the autoeo mobile by the brackets 16. Supported on the casing at the rear of the heater there is an electric motor 17 operated from the electrical system of the automobile and adapted to drive the fan blades 18 for forcing a current of of air through theradiator core from the rear to the front thereof.

The water conduit tubes 13 extend through suitable nipples 19 mounted in the dash board 15 and secured thereto by the nuts 20. to

and the spacing.

Inasmuch as it is desirable to control the direction of flow of the heated air forced through the radiator, there is mounted upon the shield 23 supported upon the front of the radiator casing 24, al defiector` 25 having a plurality of pivotally mounted shutters 26 mounted therein. The peripheral' edge ofthe defiector is circula'r and is provided with the fiange 27 extending about the corresponding circular flange 28 defining the opening in the shield 23. The defiector 25 is formed with a rectangular opening having side walls 29 to which the shutters are pivoted. By means of the shutters, the opening in the face of the radiator may be entirely closed, or partially opened as illustrated in the drawing through the medium of said shutters. Furthermore, the sllutters may be utilized 'to deflect the air 5 cular bearing portion, a deflector having aat an angle to the axis of the fan and face of the heater.

Inasmuch as it is desirable to defiect the hot air through the medium of the shutters to one side or the other, up or down, the deflector 25 is mounted to rotate upon the Shield 23, about the circular flange 28 thereof. For that purpose a handle 30 is provided for permitting the operator to grasp the said handle and rotate the deflector to any desired position.

While being freely rotatable about the Shield 23, the deflector is yieldingly held in position thereon through the medium of the spring pressed bolt 31 as illustrated in Figs. 2 and 4. The plate 32 is mounted in position to engage the inner surface of the flange 28 of the shield 23, while the deflector 25 engages the outer surface thereof. Said plate 32 and deflector 25 are then secured together so as to embrace the flange of the Shield 23, by the bolt 31, and be spring pressed into yielding engagement through the medium of the spring 33. The plate 32 is interlocked with the deflector 25 by embracing the downward extending flange 34: formed as a continuation of the side wall 29 and extending inwardly therefrom, between the lip 35 and the free edge 36 thereof.

Thus, the deflector with the pivoted shutters mounted thereon is yieldingly held in engagement with the annular flange on the Shield 23 so as to be freely rotated thereabout to any desired position of the shutters by means of the handle 30.

The invention claimed is:

1. The combination with an automobile heater having an opening through which heated air is discharged, and a Shield surrounding said opening, of a deflector associated With said shield, said shield and deflector having cooperative annular bearing surfaces surrounding said opening, and means for yieldingly maintaining said bearing portions in contact for mounting said deflector on said Shield while permitting rotative movement therebetween.

2. The combination with an automobile heater having an opening through' which 'heated air is discharged, anda shield surrounding said opening, of a deflector associated with said shield, said shield and deflector having cooperative annular bearing surfaces surrounding said opening, means for yieldingly maintaining said bearing portions in contact' for mounting said deflector on said Shield while permitting rotative movement therebetween, and an operating handle projecting from said deflector for facilitating the rotary positioning thereof.

3. The combination with an automobile heater having an opening through wh-ich heated air is discharged, of a Shield surroundng said opening provided With a cir- Le'ravea plurality of pivoted shutters mounted thereon and provided with a cooperative circular bearing portion adapted to engage and bear upon the bearing portion of said Shield, and means for yieldingly holding Said bearing portions in engagement for supporting said deflector on said Shield while permitting rotative movement thereof.

4.
